Description
Technical field
The present invention relates to cleaning agent field, in particular it relates to a kind of cleaning for the maintenance of high and low voltage electric distribution equipment on-line
Agent.
Background technology
The power equipment of longtime running, particularly, high and low voltage electric distribution equipment of on-line operation etc., in atmospheric environment by
The influence of the environmental factor such as industrial emissions, moisture, oxidation, corrosive gas and natural airborne dust in air, its surface can not
Avoid adhering to solid, liquids and gases filth particulate, and generally have certain electric conductivity and hygroscopicity.
In the case of dry weather, perhaps this kind equipment of these surfaces with dunghill remains to remain higher exhausted
Edge is horizontal.However, when running into the wet weathers such as mist, dew, drizzle, frost and ice-melt, snow melt, can be due to dirt in insulator surface
Dissolved salt in layer, acid-base class is soluble in water and forms conductive moisture film, thus leakage current can be made to be flowed through along the surface of equipment.
Because the factors such as the shape of various equipment, physical dimension influence, the current density at each position in its surface is different, and meeting exists
The bigger position of electric current is initially formed dry zone, and dry zone carries higher voltage, and when electric-field intensity is sufficiently large, electric current will
In the creeping discharge across dry section, local arc is produced.When dirty and dampness is more serious, local arc reaches or surpassed
Transcritical regime, electric arc will run through the two poles of the earth, and flashover, i.e. pollution flashover occurs, causes power outage.
Charging equipment surface is contaminated, and pollute equipment surface is wetted and voltage is that pollution flashover occurs three
Necessary condition, therefore, taken some countermeasures for any one factor, the purpose for preventing pollution flashover can be reached.
